Issue:
Is pump control mandatory for the RTUD chiller?
Resolution:
All RTUD units (systems with a remote condenser) REQUIRE that the chilled water pumps be controlled by the Trane CH530 to avoid catastrophic damage to the evaporator due to freezing.
It is strongly recommended that chilled water pump control also be used on RTWD to provide proper unit operation.
